Investigators found knives, an ISIS flag and notes inside the van used by an Isis-inspired attacker yesterday to mow down eight people and injure 12 on a bike path in New York. The suspect, 29-year-old Sayfullo Saipov, was shot and arrested by a hero cop and remains hospitalized.

A witness tells DailyMailTV he heard screams and saw bodies with tire marks on the ground of the lower Manhattan bike path where he normally enjoys breaks in his day. Watch his account.

The victims include five Argentine men who were celebrating their 30th high school reunion in New York and a Belgian mother. The carnage was halted by a cop now hailed as a hero.

Authorities raided Sayfullo's Paterson, NJ home and are scouring security camera footage to piece together a timeline, they suggest he had planned the attack for weeks. The suspect has been questioned by investigators in the hospital. Former NYPD Detective Nick Casale explains what happens next.
